If, like us, you’re passionate about realism in the details, the feel of weight, and solid shooting performance, take a look at the options that truly deserve your attention!

1. Air Pistol ASG CZ Shadow 2 Blowback Full Metal

Directly inspired by the real steel version used in competitions, the ASG CZ Shadow 2 is one of the most impressive pistols on the market, both in performance and design.

Its anodised aluminium slide, wider and more angular, gives it a more aggressive look and adds weight to the top of the pistol, helping to reduce recoil and improve shooting stability. The deeper and more pronounced serrations on the slide provide the shooter with a firmer grip when racking it.

The grip features well-defined front and rear checkering, and when combined with the CNC-machined zinc plates — which have a slimmer profile — it provides a much better wrap-around fit. The trigger guard has also been enlarged to make trigger access easier and allow smoother operation when wearing gloves. The Shadow 2 also includes a new grip angle cut, which is deeper at the beavertail.

Another highlight is the enlarged and adjustable magazine release button, which can be set in three positions, offering speed and confidence during reloads. The new design of the lower part of the trigger guard and the deeper cut at the beavertail area ensure a firmer and more natural shooting position.

2. CO2 Pellet Air Pistol Beretta M92 FS Full Metal

The Beretta M92 FS Full Metal, manufactured by the German company Umarex, is more than just a replica: it is a faithful reproduction of one of the most iconic pistols in modern history. Used by military and police forces around the world, the M92 FS stands out in 2025 as one of the best choices for those seeking realism, power, and precision.

Weighing 1,260 grams, it matches the original firearm’s weight, providing an authentic handling feel. The full-metal construction enhances durability and offers a superior tactile experience, meeting the expectations of the most demanding users.

The standout feature of this pistol is its rifled steel barrel, developed by Umarex to deliver greater shooting accuracy. This, combined with the 8-shot rotary magazine system, ensures reliable pellet feeding directly into the barrel, optimising performance with every shot.

With power reaching up to four joules, the Beretta M92 FS fires projectiles at around 120 m/s, placing it among the most powerful CO2 pistols on the market. The 12 g CO2 cartridge is housed within the metal frame and can deliver up to 60 shots per charge, maintaining consistent and strong performance.

With a full-metal body, this pistol immediately conveys a sense of robustness and quality. The blowback system delivers realistic recoil with every shot, further enhancing the authenticity of the simulation. The action is operated by a functional hammer, just like in real firearms, and the shooting mechanism is single-action, with a manual safety system.

With a velocity of 100 m/s and a capacity for 17 steel BBs (4.5 mm), this pistol offers a good balance between power and control.

4. CO2 Pellet Air Pistol Beretta M92 FS FULL METAL XX-TREME

As the name suggests, the Beretta M92 FS XX-TREME is an exceptional version of an absolute classic, the Beretta MOD. 92 FS .

5. CO2 Air Pistol Colt Defender Full Metal

The Colt Defender Full Metal is the ideal choice for those looking for a compact, robust CO2 pistol with simple operation, without compromising on power or realism. Inspired by the classic Colt design, this semi-automatic version combines functionality with a striking appearance.

Built with a metal frame and slide, it offers a weight and quality feel similar to that of a real firearm. The fixed slide helps improve gas efficiency, allowing more shots per capsule. The system uses 4.5 mm steel BBs, and the integrated magazine holds up to 16 projectiles.
